To fix the second sleep crash, try setting the Auto 4G Decoding and resize bars to "auto" instead of enable. If that doesn't work, try disable. This worked, at least with a 13900KF.
Same problem. It doesn't matter what EFI I use, whether from Olarilla or the one I create myself. Still the system crashes when going to sleep the second time. Please post if you find a solution. The issue also seems to occur on the Z690 Aero G with the F20 and F21 bios which is needed to enable support for 13000K processors
What bios are you using on your Z790 Aero G? I have the same motherboard. Mine still has F2 installed.
If I use the DSDT in this post, do I need to uncheck "rebase Regions" in the EFI that I downloaded from here for Alder Lake?
